Hello,

Does clearing of CCCR.INIT after a bus-off event is sufficient to recovery the CAN module from bus-off condition ?
Is any other steps needed ?

Can you please clarify ? I am working on the TC377 controller

Hi,

yes, correct.
User need to clear CCCR.INIT bit to start bus off recovery sequence, it will then wait for 129 occurrences of Bus Idle (129 * 11 consecutive recessive bits) before resuming normal operation.
